| Hazard Information | Back Directory | [Chemical Properties]
Phenazopyridine is a red crystalline compound. Slightly soluble in water. | [Uses]
An azo dye used in treatment of urinary tract infections. Used as an analgesic (urinary tract). | [Definition]
ChEBI: A diaminopyridine that is 2,6-diaminopyridine substituted at position 3 by a phenylazo group. A local anesthetic that has topical analgesic effect on mucosa lining of the urinary tract. Its use is limited by problems with toxicity (primarily blood disorder
) and potential carcinogenicity. | [Brand name]
Pyridium (Parke-Davis). | [First aid]
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a oneway valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 2448 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]
